okay so more questions, finally on a computer and not my phone...

can you send me a link to the brand of soil you are in?
you said ready grow but I can't seem to find what that is and what is in it...

how about the hummus? was it a certain brand or just bulk pile?

how long have they been in this soil for?

how many times have you fed the plants since they have been in this soil, and how much of each nutrient/what was the PH and EC that was given at each feeding?

what is the pot size?

when you water how much water do you give each plant/pot?

how often do you wait between waterings?

you use synthetics to feed, do you water to run off? and if so how much run off?
(one of the many reasons organics and synthetics differ is in organics you do not want run off, with synthetics you do)

in-between feedings do you just give them plain water?

have you ever given them a compost tea/earthworm casting tea?

have you ever given them a microbe booster?

what do you use to lower the PH of your water?

how often do you give them CalMag? and at what dose?



I can tell you right now its not your lights. its not the heat in your tent or humidity, there is an imbalance in the soil somewhere...

if you can do your best to answer all of those questions for me as best you can I can possibly get better idea of what you started with, what you've put in it so far, and what's going on in there...

I have no info on that, its good soil mix I used few time, I know it has some small long term fertilize (little round balls) in it.
I mixed it with 15% perlite, 15% vermiculite and 15% humus.

how about the hummus? was it a certain brand or just bulk pile?
Local brand, don't have any info on the bag.

how long have they been in this soil for?
since the 17.10 2020

how many times have you fed the plants since they have been in this soil, and how much of each nutrient/what was the PH and EC that was given at each feeding?
Every second watering, usually every 4 days.
I just go the EC meter, looks like 600-1200 ppm per feed, depend on the feed.
ph 6.5.

what is the pot size?
11L

when you water how much water do you give each plant/pot?
3.5L every 4 days, run off is 0.6L

how often do you wait between waterings?
4 days

you use synthetics to feed, do you water to run off? and if so how much run off?
(one of the many reasons organics and synthetics differ is in organics you do not want run off, with synthetics you do)
Yes, always run off.

in-between feedings do you just give them plain water?
Yes, ph 6.5.

have you ever given them a compost tea/earthworm casting tea?
no

have you ever given them a microbe booster?
on every transplant I added micorez for the roots

what do you use to lower the PH of your water?
Ph down local brand liquid, usually 1 drop per litter is good

how often do you give them CalMag? and at what dose?
2ML per litter, every second watering

I can tell you right now its not your lights. its not the heat in your tent or humidity, there is an imbalance in the soil somewhere...
I do hope you are right, cause I just bought the second light for this flowering...

if you can do your best to answer all of those questions for me as best you can I can possibly get better idea of what you started with, what you've put in it so far, and what's going on in there...

On more thing
Yesterday I feed again

BigBud 2ML for litter
Super soil mix 1ML for litter
Pk 1.2 ML for 3.5 liter

Total PPM was 1250

Runoff water PPM was:

3000 on the CBD
3500 on the Blue dream!

Few days before that I did the test for the soil as guided - took some of the soil (from upper part, coundt get to the roots zone)
put in water 24 hours, filtered and test -
It was 600ppm and 900pmm.

But now I tested the run off and the values are not in range...

What is the right value to relate to?
Runoff or soil test?

Thanks

Just writing it here cleaner:

Watering PPM was 1250 (with nutrition mixed)

Runoff water PPM was:

3000 on the CBD
3500 on the Blue dream!

Is this is an issue?

When I took soil and tested it mixed with pure water, it gave me 600 & 900.
Now I read that runoff for soil is not a good indicator?

What result should I trust?

What you do is read enough or ask around who really knows their stuff.

All opinions are not equal.

One poster in here is a pro, with years of experience in many mediums. Not me.

Being able to identify those folks is how to differentiate knowledge from guesses. As you say completely conflicting responses shows some are wrong, and few have enough info to know whats wrong.

I would never call anybody out directly, but feel free to PM me and I can tell you who to go to for the right answers.

The smartest and best growers do not argue. They know and sometimes discuss, but don't argue.

Like my signature says, "welcome to RIU" lol. That was a quote from a novice trying to get some help here, funny but true.

Nobody ever checks the calibration of their EC meter and most people talk in half ppm's that confuses everybody so most people try to talk in EC. I'm surprised your plants are surviving those high PPM numbers. Weeds can take a lot of abuse. I used to play with inaccurate cheap EC meters and screwed up some crops due to bogus readings. I finally plunked down the big bucks for a TRuncheon stick and finally have accurate readings in any scale I fancy on that day. Your plants are surviving well, they don't appear seriously over fed but there must be some kind of imbalance there. This is how we learn. Some of us just copy the success of others and use common nutes that everybody else uses to keep things simple. Keep growin' and keep learnin'.

Thank you!

I learned so much from this post.

1. I learn that EC matter for soil even I was told few times to avoid it. It good to solve issues. maybe not a must if you have your way of feeding for years, but for noobs like me, it is very important.
2. Next time I am going with clean soil only. Not from the gardening. I have better knowledge to manage with it now. First tries with clean soil cause my seedlings to die after 4 weeks... I didn't know I need to feed them so soon.
3. There can be too much light even if its in high distance from the plant. I am not sure that this is my issue, but to be on the safe side I got back to one light.


The strange thing is that I am getting very different reads from taking soil and mix them with pure water, than from runoff...
I tested again now, took some soil from the middle of the pot, from deep place. mixed with pure water, left it for one hour.
one plant 350 PPM, the other one is 600 PPM...
How can it be so different from the Runoff???

I really don't know what to do next.

Should I flash?

I have RO water.
I also have a flash solution I brought for the last week, can I use it for the flash even its not final?
Advanced Nutrients Flawless Finish Flushing Solution

Always, always get opinions, consider a plan, and act only when you are confident you can change things for the better.

Advice can be incredibly helpful or damaging. Your job is to find folks who can help and want to help. Yes some advice is terrible or not well considered. Other advice is a revelation and can fix an issue completely.

Dont stress. Think, and find a solution you think is good after some discussion.

Yes it can be confusing when you get different answers. At 35 days into flower your leaves should not be going yellow and purple which is why I said it's a nutrient issue.

From what you have said you're feeding, the NPK ratio is off. You also didn't mention what EC you're feeding at. Overfeeding can cause nutrient antagonism resulting in some nutrients being locked out. That can resemble a deficiency but isn't caused by a lack of nutrients but rather an imbalance in nutrients or too much of one nutrient. There are burnt tips on the leaves which seems to lead to not a lack of nutrients just not a mix of the right ones and too hot of a feed.

For flowering you're NPK seems rather high in nitrogen and low in phosphorus.

4-0-0
7-3-6
0-1-3

I got myself an EC meter.
I also got a PK 0-13-14 and fed twice.
Can you please tell what you think?


Watering PPM was 1250 (with nutrition mixed)

Runoff water PPM was:

3000 on the CBD
3500 on the Blue dream

But soil tested with pure water are much less,
One plant 350 PPM, the other one is 600 PPM, and in another test I got 900 & 600...

So I am really confused now...

Water with plain water. RO if that’s all you have. Tap water is preferred. Water twice and don’t flush. Flushing adds to your problems with waterlogged roots. Then check a runoff EC.

Thanks,

I have RO, but I have TAP also.
Should I wait for it to dry or to water even if I fed yesterday?

Mine was reading the same I flushed it low. then my next feed I watered with just ph'd water got run off it was low still so now I'm going to start adding my feed back in next feed get it back up to ideal I've had no deficiencys since flushing it low yet blue dream photos

I also used ppm meters at 1st. But then I had 4 ppm meters & checked the same nute mix & they all had different readings. Some 150 ppm difference. Granted they were cheapos & not Blue Lab. I don't see many new growers with Blue Labs so the ppm pen thing is pretty inaccurate.
That's why I learned to read the leaves. Blue Labs are about $150 & up at my Hydro Store. Kind of expensive for what it does.

You don't need to spend $150 or buy the Blue Lab brand, plenty of other good meters out there. I bought two used HM Digital COM-80's for under $10 each from ebay and a bottle of calibration solution.

Everywhere you look for flowering recommended ppm

What are the best pH and PPM Levels for Growing Marijuana?

Becoming professional growers cannot ignore pH. Maintaining steady pH and PPM levels is crucial to a successful grow.

Only synthetic fertilizers. There is also 15% humus in the soil.


Cal mag extra NPK 4-0-0
https://www.amazon.com/Advanced-Nutrients-Sensi-Cal-Mag-Nutrient/dp/B00P8EVEHG/

Bio Nova soil super mix - NPK 7-3-6
Amazon.com : Bio Nova BNSSM5L Soil SuperMix Liquid Fertilizer, 5 Liters : Garden & Outdoor

Big Bud - NPK 0-1-3
https://www.amazon.com/Advanced-Nutrients-Liquid-Fertilizer-1-Liter/dp/B001GBOAQC/ref=sr_1_1?dchild=1&keywords=Advanced+Nutrients+Big+Bud&qid=1588160569&sr=8-1&th=1

I added only now (by mistake) Bio nova PK 13-14 (0-13-14) instead of the soil super mix.

Cal mag + Big Bud + PK - All of them in one feed gave me with tap water 1250 EC.

So I don't see any problem with too much nutrition.

I think its a light stress. not heat, light.
I turned off one of the leds, and now I am with 120W.

I will update.
Click to expand...
I don't think it's the cause of your problem, but 240w in a 2x2 is VERY high for an efficient light. Around 30-35w/square foot is common with efficient white lights and 50 with inefficient blurples.

update:

I gave water only and then only pk 13-14.

Maybe it was genetics after all...
Cause they are looking goooood!

End of 8 week since flip.
I think they got 2 weeks to go.
